This place was by far my best hostel experience in Thailand and one of the best in my life. In a very good location, with a magnificient view on the terrace. Rooms are a bit too small for my liking but it wasn't much of a problem. The whole place was very neat and clean.
They took us and some other people staying at the hostel on a walking+boat tour around the city upon our arrival (completely free of charge) which was great. Our guy Stefani (one of the front desk staff member and also our guide at the tour) and his friends were great hosts.
Oh, I can't recommend this place enough! You should definitely consider this place for your visit to Bangkok. A great place for its price!
